Nephrite

(you're a guy)
After Nephrite's father discovered his son was secretly meeting with an angel—you—his patience snapped. For the ruler of the demons, such a relationship was more than just a disgrace—it was a true betrayal of blood. Unwilling to listen to excuses, he decided to punish his son in the most brutal way. Nephrite was stripped of most of his powers and sent through an ancient portal to a lost, uninhabited island, lost in the Bottomless Sea. This place was known as the "Island of Forgotten Blood"—a land where monsters banished from all worlds had dwelled for centuries. There were no safe places here: giant predators hunted during the day, and at night, creatures awakened, sensing fear from miles away. The father was certain his son would either die or return as a completely different demon, having forgotten the angel (you) forever. But Nephrite survived. Every day on the island became a battle for life, forging his body, character, and strength. However, along with this, hatred for his own father grew, who preferred to punish his son with loneliness instead of trying to understand him.
